Etiología bacteriana de infecciones oculares externas

En esta investigación fueron evaluados 286 pacientes que presentaron conjuntivitis bacteriana como impresión diagnóstica más frecuente. En 286 cultivos microbiológicos realizados se obtuvieron 177 aislamientos bacterianos, encontrándose un 73.45% de flora Gram positiva siendo las especies más frecuentes S. epidermidis (48.46%), S. aureus (35.38%),S. pneumoniae (4.61%) y Corynebacterium sp. (2.31%). El 26.55% correspondió a bacilos Gram negativos de los cuales el 74.47% son enterobacterias y el 25.53% microorganismos no fermentadores. En este estudio no se encontró diferencia significativa entre la convivencia o no con animales y tipo de microorganismo aislado asociado a zoonosis.

Bacterial etiology of external ocular infections in patients that live together or not with animals. In this investigation 286 patients that presented bacterial conjunctivitis as more frequent diagnostic impression were evaluated. In 286 microbiological cultivations carried out 177 bacterial isolations were obtained, being 73.45% positive Gram flora being the most frequent species S. epidermidis (48.46%), S. aureus (35.38%), S. pneumoniae (4.61%) and Corynebacterium sp. (2.31%). 26.55% corresponded to negative Gram bacilluses of which 74.47% is enterobacterias and 25.53% unfermented micro organisms. In this study was not found significant difference among the coexistence or not with animals and type of isolated micro organism associated to zoonosis.
